Research: Regulation of cell migration along natural extracellular matrices during wound repair; cytoskeletal function and cell-matrix interactions during mitosis and cell movement.

Sheldon Gordon investigates mechanisms regulating corneal endothelial wound repair along its natural basement membrane (Descemet’s membrane), as well as the accompanying cytoskeletal changes and cell-matrix interactions that also occur during cell movement. The endothelium is a cell monolayer that is responsible for maintaining corneal hydration and thus tissue transparency. Recent work has focused on a soybean agglutinin (SBA) binding protein on the cell surface that appears in situations involving either stress or injury. Interfering with this protein prevents the reformation of cell-cell contact, disrupts the actin cytoskeleton and alters the expression of ZO-1, a cell junction protein during wound repair. In addition, although cell migration appears unaffected, cellular processes become blunted and fail to significantly extend from the cell body. Additional work on cell motility in his laboratory has also explored the roles of actin and tubulin during injury-induced cell movement and protease involvement in migration. His research has been funded by the National Eye Institute and the Michigan Eye Bank, and he has been an invited speaker at the 6th 7th, 8th and 14th meetings of the International Congress of Eye Research, and at the I st, 2nd and 3rd Congresses of Cellular and Molecular Biology. In addition, Dr. Gordon served on the editorial board of the journal Cellular and Molecular Biology and currently serves on the editorial boards of the Journal of Cytology and Molecular Biology and Journal of Cell Biology and Histology.
